Abstract (en)

At least two asynchronous AC induction electrical machines in parallel connection with the power source are respectively made with the main winding and control winding for operating the electrical machines, wherein the individually driven loading operations of the two electrical machines in cross-interlockingly parallel connection being parallel connected with the power source are led by the changes of individual electrical machine driving loading statuses to appear variable impedance operation so as to change the end voltage ratio between individual electrical machines in cross-interlockingly parallel connections.
